Awful service by online upgrade department

Online upgrade what a disaster. I ordered my online upgrade 3 weeks ago, I might have entered my address incorrectly or it was captured incorrectly. I realised this when the RAM courier phoned me for delivery. I informed him of the correct address but was told I needed to contact Vodacom to change the address. I phoned the online department a couple of times. They were very unhelpful, not returning my calls. They assured me that they would contact RAM with my correct address, this never happened despite 3 phone calls and eventually my phone was sent back to the warehouse. Since then I've have had no communication from Vodacom to rearrange delivery. Eventually I went to a Vodacom shop to see if I could do my upgrade there. They phoned the upgrade department to ask them to cancel my upgrade so they could do it for me. The online department assured me it would be canceled in 24h. I went back to the shop and was told it's still not canceled. It's a week later. I actually don't know what to do anymore. I can't upgrade at the store because the online upgrade is still not canceled, despite numerous phone calls. I've been a loyal Vodacom customer for many years and the treatment by your call center staff has been awful.
